DIE FOR ATTACHING GROMMETS TO HEAVY FABRICS.

SPECIFICATION forming part of Letters Patent No. 242,391, dated May 31,1881.

Application filed December 13, 1880.

set the grommets to the fabric. the same bein g retained between themaleand female parts of the grommets by the pressure of the lips orflanges of the grommets. It has been found,

however, that this mode of fastening the grommets is not snfficient toprevent the loosening or fraying out of the fabric from between the lipsor flanges of the grommets, which feature has formed a serious objectionto these grommets.

The object of this invention is to apply the grommets by means ofimproved dies, so that a more reliable and intimate connection isobtained between grommets and fabric.

The invention consists in providing either one or both of the diesemployed for attaching the grommets to the fabric with projecting teeth,for the purpose of indenting or barbing the lips or flangessimultaneously with the setting of the grommets, so that they bind moresecurely on the fabric and prevent their playing loose therefrom.

In the accompanying drawings, Figure 1 represents a side elevation,partly in section, of the dies employed in setting the grommets; andFigs. 2 and 3 are, respectively, a top and a bottom view of the femaleand male part of the die; and Figs. 4 and 5 are a top view and avertical longitudinal section on line 0041, Fig. 1,0f a grommet set bymy improved dies.

Similar letters of reference indicate corresponding parts.

A in the drawings represents the lower or female, and B the upper ormale, portion of my improved die for attaching grommets to heavyfabricssuch as leather, canvas, duck, &c. The male part of the grommetis placed on a central movable and spring-acted tongue, a, of the femaledie A, which tongue is forced down into the lower die by a fixed tongue,I),

(No model.)

of the upper die, B, after the fabric and female part of thegrommet isplaced in position on the female part A of the die. The fixed tongue I)of the male die B entersinto the cor responding slots of the male andfemale parts of the grommet, and causes the setting of the grommet andits connection to the fabric in the usual well-known manner.

The new feature of my die consists in providing either the female part Aor the male part B, or both, with projecting teeth d, which, when usedin both dies, are preferably so arranged that the tecth of one diealternate with those of the other. These projecting teeth d serve forthe purpose of indenting or barbin g one or both lips or flanges of thegrommet, so as to cause the raised parts or barbs to enter into thefabric. By these irregularly-punchedup portions or barbs the grommetsbind more seculely upon the fabric and prevent the same from gettingloose from or fraying out of the grommet.

The projecting teeth may be used with any shape of die and grommet,whether they are round, square, oblong, or oval, the essential featurebeing the indenting or barbing of the lips or flanges of the grommets bymeans of the teeth of the dies, so that a more reliable and intimateconnection of the same with the fabric is obtained. As this isaccomplished simultaneously with the setting of the grommets by thedirect action of the dies, no extra labor is necessary therefor.

Havin g thus described my invention, I claim as new and desire to secureby Letters Patent- A die for attaching grommets to fabrics, in which themale or thefemale part, or both parts, are provided with projectingteeth around the central tongues, to indent or barb the lips or flangesof the grommet and cause it to adhere rigidly to the fabric,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention 1 have signed myname, in presence of two witnesses, this 6th day of December, 1880.

HENRY STEPHENS.
